The present invention relates to new and useful improvements inattachments for corn planters and other agricultural implements of thewheel supported type and has for its primary object to provide, in amanner as hereinafter. set forth, novel means for covering the tracksleft by the wheels and for forming pockets in the soil for retainingwater or moisture and preventing erosion.

Another very important object of the invention is to provide anattachment of the aforementioned character for agricultural machinesembodying a novel construction and arrangement whereby the earth workingelements may be conveniently raised, lowered and adjusted as desired.

Still another very important object of the invention is to provide anattachment of the character described which may be expeditiously mountedon a conventional corn planter or other implement without the necessitj7of making structural alterations therein.

Other objects of the invention are to provide an attachment foragricultural implementswhich will be comparatively simple inconstruction, strong, durable, highly ern/cient and reliable in use,compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will `become apparent from a study of thefollowing'specifcation, taken in connection with the accompanyingdrawings wherein like characters of reference designate correspondingparts throughout the several views, and wherein:

Figure 1 is a View in side elevation, showing an embodiment of thepresent invention mounted for operation on the rear end of a cornplanter.

Figure 2 is a top plan `View thereof.

Figure 3 is a detail view in perspective of one of the adjustable discaxles.

Figure 4 is a view in side elevation of one .of the multiple bladediscs.

Figure 5 is a view in horizontal section, taken substantially on theline 5--5 of Fig. 4.

Figure 6 is a top plan View of a modification.

Figure 7 is a perspective View of a portion of the modication shown inFig. 6, showing the elements separated.

Referring now to the drawings in detail, it will be seen that thereference numeral I designates generally a portion of a conventionalcorn planter which includes a vframe structure 2 mounted on wheels 3.Mounted for raising and lowering on the forward portion of the framestructure 2 is a planter shoe 4 of the usual construction. A hand lever5 is operatively connected to the shoe for raising and lowering same.

Pivotally mounted for swinging movement on the frame I is a pair ofrearwardly and downwardly extending arms 6. Mounted on the free ends ofthe arms 5 is a transversely extending tubular member l. The arms 6 areprovided with eyes 8 on their rear ends in which the tube 'I is securedby set screws 9.

Removably and adjustably mounted in the end portions of the tube l areangular bars I0. Bolts II secure the angular bar I0 in adjusted positionin the tube 1. Mounted for swinging adjustment on the free end portionsof the bars l are diverging axles I2. As best seen in Fig. 3 of thedrawings, the axles I2 are formed to provide discs I3 on one end havingarcuate slots I4 therein which accommodate bolts for securing said axlesin adjusted position on the bars Il).

Mounted for rotation and sliding adjustment on the axles I2 are pairs ofrearwardly converging discs which are designated generally by thereference numeral I5. Referring now to Figs. 4 and 5 of the drawings, itwill be observed that the discs I5 include flanged hubs I6 havingmounted thereon a plurality of blades I'I. Collars I8 areprovided on theaxles I2 for retaining the discs I5 in adjusted position. The collars I8are secured in adjusted position by set screws I9.

Mounted on the rear end portion of the frame structure'Z is a bell cranklever 25. Adjustably mounted on one end portion of the bell crank lever2l] is a substantially V-shaped hanger 2I the ends of which areconnected to the tube l. Pivotally mounted on the planter lever 5 is ahand lever 22. A link 23 operatively connects the bell crank lever 2!)to the hand lever 22.

Rigidly mounted on the planter lever 5 is a toothed segment 24. A latch25 on the lever 22 is engageable with the segment 24 for releasablylocking the lever 22 to the planter lever 5 for swinging movement inunison therewith. It will be observed that the lower kend of the lever22, to which the link 23 is connected, extends below the pivot 26` ofthe planter lever 5.

It is thought that the operation. of the device will be readily apparentfrom a consideration of the foregoing. As the machine travels over theground the rearwardly converging pairs of discs I5 at the rear of thewheels 3 throw the earth over the tracksleft by said wheels. As thediscs I5 rotate the spaced blades I 1 thereof form pockets or damsalong, the opposite side portions of the tracks for retaining water ormoisture and. preventing erosion. By operating thelever 22 independentlyof the lever 5 the discs I5 may be raised and lowered to operate at thedesired depth. With the lever 22 locked against swinging movement to thelever 5 through the medium of the elements 24 and 25, the discs I5 maybe raisedv and lowered simultaneously with the planter shoe 4 byactuating said lever 5. It will be observed that the hanger ZI may beadjusted on the bell crank lever 20, also that the link 23 is adjustablyconnected to said bell crank lever. By loosening the bolts I I theangular bars I 0 may be conveniently adjusted for machines of differentwidths or to meet other conditions. This also facilitates removal of thediscs I5 fro-m the machine when desired. Through the medium of thecollars I8 the pairs of discs I5 may be adjusted toward or away fromeach other as desired. Then, the adjustable connections of the axles I2to the angular bars I0 permit the angle of the pairs of discs I5relative to each other to be conveniently regulated. Suitable greasefittings 2'I are provided at desired points, as on the hubs I6, forlubricating the moving parts of the attachment.

Referring now to Figs. 6 and 7 of the drawings, it will be observed thatthe reference numeral 28 designates generally a transverse bar or memberwhich is mounted on the arms 6. The bar 28 includes a pair ofoverlapping sections 29 which are adjustably secured together, as at3i).

Mounted for swinging adjustment on the ends of the bar 28 are sockets3l. The outer ends of the bar sections 29 and the socket members 3| areprovided with complemental toothed discs 32 (see Fig. 7) which areapertured to accommodate bolts 33.

Mounted in the socket members 3| are removable axles which aredesignated generally by the reference numeral 34. The axles 34 includeangular inner and outer sections 35 and 33, respectively, which arehingedly connected for swinging.;` adjustment relative to each other at3`I.` The inner axle sections 35 have one end portion removably securedinthe socket members 3| by bolts 38.

'I'he operation of the embodiment of the invention shown in Figs. 6 and7 is substantially similar to the embodiment illustrated in Figs. 1 to 5of the drawings. It may be well to here state that the discs I5 arejournaled on the sections 35 and 35 of the axles 34. Thus, the discs arearranged in rearwardly converging pairs. By lengthening or shorteningthe sectional bar 28 in the eyes 8 of the arms 6 the discs may be movedinwardly or outwardly for machines of different widths. Through themedium of the hinge connections between the axles 34 and the lbar 28 thepairs of discs may be adjusted as a unit. Then, through the medium ofthe hinge connection 31 between the axle sections 35 and 36 the angle ofthe pairs of discs relative to each other may be regulated as desired.The discs are rotatable and slidable on the axle sections 35 and 36 ason the axles I2.

It is believed that the many advantages of an agricultural implementattachment constructed in accordance with the present invention will bereadily understood and although preferred embodiments of the device areas illustrated and described, it is to be understood that furthermodifications and changes in the details of construction may be resortedto which will fall within the scope of the invention as claimed.
